BOILER-DISINCRUSTATING COMPOUND.

No Drawing.

To all whom it may concern.-

Be it known that I, Rosnnno LADRON on GUEVARA, a citizen of the Republicof Mexico, residing in Vera Cruz, Mexico, have invented a new andImproved Boiler-Disincrustating Compound, of which the following is afull, clear, and exact description.

Among the principal objects which the present invention has in view are:To provide a compound which prevents the accumulation of scale or otherincrustating coatings in boilers; to provide a compound the neutralizingeffect of which is calculable and may be added to the water of theboiler in direct ratio to the water consumption thereof; and to providea compound which is simple, economical and non-destructive.

The compound hereinafter set forth as possessing the qualities abovedescribed consists of the following ingredients, combined and preparedin the proportions as tabulated, to wit Lime or calcium oxid -i 100kilos. Brick earth or powdered brick 20 Refined petroleum 15 Juice ofagave leaves 35 Carminic acid 1 I-Iydro-chloric acid 2 The lime isunslaked, and the pulverized brick are admixed and ground until they arevery fine. The petroleum and juice of the agave leaves are then firstmixed with each other, and added to the pulverized lime and brick dust.The result of the mixture is a paste. Into this paste is incorporatedthe carminic and hydro-chloric acids. The paste resulting from thismixture is then sundried until it becomes hard or brittle. In thiscondition is it pulverized, producing a pink powder, which is thencanned, packed or otherwise made ready for transportation and use. Inits use the formula which it has been found by experience as mostdesired is that 10 grams of the powder is first mixed with 2 liters ofwater in any suitable vessel. The water and powder mixed in the abovestated proportion is now introduced into the boiler, the quantitypreferred being the 2 liters of water with the powder admixed for eachhorse power of the boiler.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed May 3, 1910. Serial No. 559,167.

It will be found that after 72 hours of ebullitio-n the inerustationwhich may have accumulated in the boiler will precipitate or dissolve.This operation may be repeated at intervals of approximately one monthapart. The compound is also used for de stroying the soot formed bygases in the product of combustion in fire flues or conduits. In the useof the compound for the clearance of such agents, the proportion ofwater and powder is maintained as above stated, and is applied betweenthe fines or fire conduits, closing and charging said conduits in asuitable manner so that the compound, on passing through the upper finesmay escape through the lower. The time required for the cooling of theboiler will suffice for destroying the soot, the compound beingintroduced after the fire is drawn.

The disincrustating compound, when mixed and applied as above stated,obviates the dangers of explosion, purifies the steam and produces alarger efficiency thereof, resulting in a considerable economy of fuel.

The compound is applicable to all steam boilers, irrespective of thecharacter of the water used.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. Aboiler disincrustating compound,consisting of calcium oxid and baked clay mixed; refined petroleum; thejuice of agave leaves; carminic acid; and hydro-chloric acid; mixed insuitable proportions to form a paste.

2. Aboiler disincrustating compound,consisting of 100 parts calciumoxid; 20 parts of pulverized baked clay; 15 parts of refined petroleum;35 parts of the juice of agave leaves; 1 part of carminic acid; 2 partshydro-chloric acid; all mixed to form a compound.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
